Well one can say that about just about EVERY aspect of life, couldn't they?
I think it has a lot to do with how self-aware and self-examined one is, and sometimes age clears a lot of these issues up because you've had a lot of years to find out who you are, likes and dislikes.
I really *do* know what I like. I don't have to go out there and try out everything......if I did that with cars, shoes, vapes, travel, food, geography, social life, dancing, pet ownership, sports.........I'd be utterly broke and most likely,
no closer to being happy than I am now.
The idea of being happy with what you have, and general contentment, is not necessarily a bad thing you know. We all know when we are in a rut......and we all know when we've hit our sweet spot in life.
If you don't reach any of those milestones, then by all means, KEEP TRYING TIL YOU DO.
But just to keep trying out stuff, because it's there and available to purchase.......not really into that myself.
